I noticed that the default offset when loading the ts72xx_isa16550
driver is 0x3e8. Since, with the COM4 configuration of the TS-MODEM2
board, its offset is 0x2e8, I just needed to add the offset parameter to
the call of modprobe (e.g. "modprobe ts72xx_isa16550 io=0x2e8 irq=40"),
and check the dmesg from boot to see the line "serial8250: ttyS0 at MMIO
0x11e002e8 (irq = 40) is a 16550A" to know that ttyS0 is the device to
use in minicom.

I have modprobed ts72xx_isa16550 irq=40 to use the serial interface

I have a TS-MODEM2 plugged into a TS-7260. The jumpers are set all
off, except for JP5 (i.e. COM4, IRQ7).
I tried using minicom to communicate to the modem on the board by
using ttyS1 (I have previously used a TS-GSM1 that was configured as
COM3, and it used ttyS0), but I do not get a response from the board
(MultiTech Cell CDMA; 115.2kbaud, 8-N-1; hardware flow control).
Does anyone have experience using this board who can give me pointers
on how to interface with it? I'm assuming that I can interface using
the ISA bus.
